Abstract

The invention discloses an event model space-time information representing and processing method orientated towards a CPS. The method includes the following steps that a space-time information representing method for a CPS event model is defined, and the CPS event model comprises a basic event model and an extension information set; the basic event model is defined and used for representing the most basic event information, from a data source, of one event; the extension information set is defined, and various types of attribute information possibly carried by the CPS event are defined; mapping and extension are performed from the basic event mode to the extension information set; space-time information of the event is obtained; an event condition based on the space-time information is judged, and whether CPS response action is generated or not is determined according to the judgment whether the CPS event received by a capturer meets a certain constraint condition or not. According to the scheme, the problems that in the process of CPS application, semanteme of space-time data of the event is diversified, and therefore application software on the upper layer is difficult to directly apply can be effectively solved.

Description

technical field

[0001] The invention relates to the field of cyber-physical fusion, in particular to a CPS-oriented event model spatio-temporal information representation and processing method. Background technique

[0002] CPS is a heterogeneous system that integrates computing capabilities and physical processes. By embedding computing and communication components in widely distributed physical devices, computing processes and physical processes interact with each other in the process of adaptive perception, interaction, and action through feedback loops. To realize the reliable, real-time and efficient monitoring, coordination and control of physical processes by embedded computers and networks. Events are ubiquitous in the CPS system. Event monitoring and behavior decision-making operations in CPS should be accurate and timely to ensure the expressibility of time and space information, and provide corresponding event processing methods.
